What is the meaning of construction film?

Building film is made of PET (polyester film) substrate, using multi-layer metal sputtering technology and vacuum technology and ion technology as well as film physics and fine chemical technology, so that it has high thermal insulation efficiency, high tension, high elongation, strong Anti-acid properties. And the color is naturally rich. The test results show that it can block 81% of solar energy; when the outdoor temperature is 38 ° C ~ 39 ° C, the temperature is 3.5 ° C lower than that of ordinary glass, saving more than 30% of the power consumption of air conditioners. It is a high-tech and energy-saving safety Material.
The main purpose of architectural membrane is energy saving and heat insulation, and it is equipped with anti-ultraviolet and safety functions. Architectural films can also be divided into heat reflective films and low emissivity films. Heat reflective film, this architectural film is attached to the glass surface so that the room can transmit visible light and near-infrared light, but cannot transmit far-infrared light. Therefore, enough light enters the room, and most of the solar heat is reflected back, so that the indoor temperature will not rise too much in the hot summer, thereby reducing the indoor air conditioning load, saving air conditioning costs and saving energy. Low-E film, this architectural film can transmit a certain amount of short-wave solar radiation, so that solar radiant heat enters the room and is absorbed by indoor objects; at the same time, it can reflect more than 90% of the long-wave infrared radiated by indoor objects. . Low-E film can make full use of solar radiation and long-wave radiation energy of indoor objects. Therefore, it can be used in cold areas and heating buildings to achieve thermal insulation and energy saving effects.
Architectural film, as the name suggests, is used in residential, office buildings, commercial buildings and other building door and window glass, curtain wall glass, decorative glass and other locations to meet various needs in different environments. From a professional point of view, architectural film is a multi-layer polyester film, which is manufactured by vacuum multi-layer technology, ion technology, film physics, and fine chemical technology. It has good strength and durability, and has different processing methods. different functions.
Architectural membranes are roughly divided into three categories according to their application scope: energy-saving membranes, safety explosion-proof membranes, and interior decorative membranes. Has the following six functions:
Efficiency increase and energy saving - reduce heat inflow in summer and reduce air-conditioning costs, thereby exerting energy efficiency;
Improve indoor environment - improve indoor comfort, less hot and dazzling light;
Beautify the appearance of the building - make the building and living room lasting and new, different styles echo and complement the interior, and beautify the appearance of the building;
Ultraviolet isolation - can greatly reduce solar heat and visible light entering the room, isolate ultraviolet rays, protect building interior items from damage, and reduce harm to the body;
Safety - Ordinary glass will be damaged and produce a large number of glass fragments when encountering strong winds, rainstorms and impacts, which will cause harm to people and property. After filming, even if the glass has been broken into pieces, it will be bonded into a whole to improve safety;
Privacy - The one-way perspective function satisfies the two-way demand for viewing the external scenery while protecting privacy.
